Your antibodies are high this is Hashimoto's, (also known by medics here in UK more commonly as autoimmune thyroid disease).

About 90% of all hypothyroidism in Uk is due to Hashimoto's

Did your GP organise these tests? Or did you get them privately? i am guessing they are private ones.

They clearly show you need starting on Levothyroxine. 50mcg is standard starter dose, bloods will need retesting after 6-8 weeks and dose increased in 25mcg steps, retesting each time, until TSH is around one and FT4 towards top of range and FT3 at least half way in range

Hashimoto's affects the gut and leads to low stomach acid and then low vitamin levels

Low vitamin levels affect Thyroid hormone working

Clearly yours are terrible
